IMPROVEMENT IN SPINNING-ROLLERS.

Specification forming part of Letters Patent No. 46,896, dated March 21,1865.

To all whom it may concern:

Be it known that we, ISAAC GooDsPEED, of Norwich, in the county of NewLondon and State of Connecticut, and GURDON S. GooDsPEED, of Providence,in the county of Providence and State of Rhode Island, have invented anew and useful Improvement in Rolls for Drawing, Roving, and SpinningMachinery; and we do hereby declare that the following is a full, clear,and exact description ofthe same, reference being had to theaccompanying drawings, forming part of this specication, in which-Figure 1 is a longitudinal view of a shaft and two rolls. Fig. 2 is atransverse section of the same.

Similar letters of reference indicate corresponding parts in bothfigures.

It has been long desirable to find some more durable substitute forleather for covering the top rolls of drawing, roving, and spinningmachinery, and though many substances have been tried none haveheretofore been found suitable in all respects. This invention consistsin constructing the surf-aces of such rolls with cork, arranged andapplied in the manner hereinafter described.

` To make a corkcovered roll we iirst make or obtain a shaft, A, ofsuitable size, turned perfectly true, with suitable journals and withone or more xed collars, a c, according to the number of rolls to beprovided thereon, and fitted with a number of washers, b b,corresponding with the number of collars, the said washers to be securedat suitable distances from the collars, according to the desired lengthof the operating-surfaces of the rolls, by means of pins c c, insertedinto holes drilled transversely through the shaft. We then take rings dd, of cork of suitable diameter and thickness, having their interiors ofa size to fit tightly to the shaft A, and press them onto the shaft Aand up to the collars c c, and afterward put on the washers, which wepress up against the cork with a sufcient degree of pressure to compressthe cork to the greatest possible degree, and secure the said washersand the cork byinserting the pins c c.

' When two or more rings of cork are necessary for a roll to obtain thenecessary length, the faces are cut perfectly smooth and of such formthat their union will be imperceptible. Having thus secured the cork weplace the shaft in a turning-lathe and turn the exterior ofthe corkperfectly smooth and of the requisite diameter.

When more tha-n two rolls are required on one shaft, we substitute forthe fixed collars c c of the additional rolls, loose collars, which areheld in place by pins similar to c c, or other suitable stops.

It is of considerable importance to cut and apply the cork that thecrevices or ilaws which are common in this material will be parallelwith the axis of the roll, as by that means we avoid any crevicesruiming in a circumferential direction which would be prejudicial to theuse of cork for such purposes.

Instead of pins c o, nuts may be used to secure the washers.

We are aware that rolls for other purposes have been constructed orcovered with cork arranged as above described. Our invention isrestricted to rolls employed for spinning and drawing for cotton-mills.

What we claim as our invention, and desire to secure by Letters Patent,is-

A roll for drawing, roving, or spinning maf chinery, constructed with asurface of cork applied with its tlaws or interstices parallel with theaxis, and compressed and turned as hereinbefore described.
